Conifera, 314 (1900). 



A tree, occasionally attaining 40 to 50 ft. in height, with a short trunk 6 to 9 ft. 

 in girth. Bark, buds, branchlets, and foliage, as in P. Balfouriana, though in culti- 

 vated specimens the young branchlets of P. aristata differ in being covered with 

 a dense reddish brown pubescence ; whilst both on wild ' and cultivated trees of 

 P. aristata the leaves are remarkable in being dotted over their outer surface with 

 resinous exudations. 



Cones subterminal, spreading, sessile, about 3 in. long, ovoid-conic ; scales thin, 

 oblong-cuneate, f to 1 in. long ; apophysis rhomboidal, transversely keeled, with a 

 slender incurved brittle prickle, nearly \ in. long. Seed light brown, mottled with 

 black, \ in. long ; wing \ to \ in. long. 



This alpine species is widely distributed from the eastern range of the Rocky 

 Mountains in Colorado westward through the mountains of southern Utah, and 

 central and southern Nevada, southwards in the San Francisco peaks of northern 

 Arizona, and in the mountains of south-eastern California. It grows on rocky or 

 gravelly slopes, forming the timber line in these mountainous regions at 9000 to 

 1 2,000 ft. elevation, and producing a soft light wood, which is occasionally used for 

 fuel and in the mines. 



This species was discovered 2 in 1861 by Dr. Parry on Pike's Peak in Colorado, 

 and plants raised from seed sent by him to Boston had only attained 18 in. in height 

 at the end of thirty -five years. 3 Seeds were sent 4 in 1863 from Colorado to 

 England, and small trees may be seen in botanic gardens, the specimen at 

 Glasnevin, which has produced cones of late years, being about 15 ft. high. The 

 best specimen we have seen in England is one at Hardwick, near Bury St. 

 Edmunds, which is about 25 ft. high by 2 ft. in girth. It was planted by Sir Joseph 

 Hooker, and bore cones in 1905 when Elwes measured it. There is also one at 

 Aldenham about 20 ft. high which bore cones in 1908. There are also specimens 

 at Ponfield, Herts, and at Ochtertyre, 6 in Perthshire. (A. H.)
